Skills:
Meteor/Flare
Fireball
Rotgort's Invocation
Phoenix
Elemental Attunement [E]
Fire Attunement
Aura of Restoration
Rez Sig
Attributes:
Just give all to Fire Magic and Energy Storage

Weapon:
Well, Staff with +20% Enchants would be nice.
How to use it:
It's very simple. You are using Elemental Attunement, than Fire Attunement and than cover it with Aura of Restoration. The trick is to keep Elemental and Fire Att up. In that way your mana degeneration will be very very small :P You can just spam other skills.
It may look too simple, but it works

I'm open to sugestions to make this build better (or just tell me if it suck :P)
